BIOMEDICINE: Separation of Conjoined Hormones Yields Appetite Rivals
Ruben Nogueiras and Matthias Tschöp
In their Perspective, Nogueiras and Tschöp discuss the study of Zhang et al. that has identified obestatin, a new hormone regulator of energy balance. Obestatin suppresses food intake, body weight gain, and gastrointestinal motility in rodents. The paradox is that obestatin is derived from a precursor peptide that also yields ghrelin, a hormone that increases appetite and body weight.
